ABSTRACT:
A tubular, fluid-controlled bending neck is provided for an elongated flexible probe, such as a video borescope. An elongated tubular elastomeric bladder is fitted to a proximal connector that fits onto a distal end of the probe insertion tube, and a distal fitting seals the distal end of the bladder. A tubular braid is disposed over the bladder to confine the same and is mechanically attached to the distal fitting and to the proximal connector. The connector provides communication of fluid pressure from a controlled fluid pressure source to the interior of the bladder. An elastically bendable, but axially substantially incompressible spine is disposed at the interface between the bladder and the braid. This spine is preferably set or biased to be curved into one bending direction. As fluid pressure is applied to the bladder, the bladder inflates laterally. This shortens the braid on the side away from the spine, thereby bending the neck in the opposite direction. By applying a pressure intermediate between a zero pressure and the pressure required for full bending the bending neck will assume a straight orientation.
